...after spending so much time on so many sites getting the category sidebar to permanently expand, now I need to learn how to shrink it back down again! LOL

I've been using CH_Category, and it works great for expanding the category sidebar. But there are way too many subcats on this site (http://scentsandsilver.com/products/) and we haven't even finished adding subcategories yet.

How can I collapse the categories again, so that the subcats only show up when someone does a mouseover on the sidebar?

Thanks!!
